Italian slang for lazy person with a small dick. In some areas its used to describe someone unusually skinny, pedophilia, and I've even heard homosexual. The word has different meaning based on where its said, but it all references Italians.
After a threesome with some extremely hot girls, Jason, who was not performing up to satisfaction, was told that he was a Laposta.
